Entering Form Information without Opening the SharePoint List
Learn how to obtain SharePoint list form information on a new item form without allowing the end user to interact with the list itself.
There are some scenarios where you might need to collect information in a SharePoint list, but at the same time, you would not want the end user to interact with the list itself.
In such a case, you can configure it as follows:
Add the form URL, which should be something like this template (e.g., https://YourTenant.sharepoint.com/sites/YourSite/Lists/YourList/NewForm.aspx), to a default out-of-the-box SharePoint Quick Links or Button web part. Clicking it will open the NewForm in the browser.
In the NewForm actions configuration itself, instead of using the default Save action (which has Save Form and Close Form action steps), you could replace the Close Form action step with the Open Web Page action step.
This replacement will ensure that when the user saves the form, it re-opens the new web page of your choice. This way, the users don't see the actual SharePoint list after the item is saved. You may also choose to add as many available action steps to fit your scenario.
